RULE §116.150New Major Source or Major Modification in Ozone Nonattainment Areas

(a) This section applies to all new source review authorizations for new construction or modification of facilities or emissions units that will be located in any area designated as nonattainment for ozone under 42 United States Code (USC), §§7407 et seq. as of the date of issuance of the permit, unless the following apply on the date of issuance of the permit:

  (1) the United States Environmental Protection Agency (EPA) has made a finding of attainment;

  (2) the EPA has approved the removal of nonattainment New Source Review (NSR) requirements from the area;

  (3) the EPA has determined that Prevention of Significant Deterioration requirements apply in the area; or

  (4) the EPA determines that nonattainment NSR is no longer required for purposes of antibacksliding.

(b) The owner or operator of a proposed new major stationary source, as defined in §116.12 of this title (relating to Nonattainment and Prevention of Significant Deterioration Review Definitions) of volatile organic compound (VOC) emissions or nitrogen oxides (NOX ) emissions, or the owner or operator of an existing stationary source of VOC or NOX emissions that will undergo a major modification, as defined in §116.12 of this title with respect to VOC or NOX , shall meet the requirements of subsection (d)(1) - (4) of this section, except as provided in subsection (e) of this section. Table I, located in the definition of major modification in §116.12 of this title, specifies the various classifications of nonattainment along with the associated emission levels that designate a major stationary source and significant level for those classifications.

(c) Except as noted in subsection (e) of this section regarding NOX , the de minimis threshold test (netting) is required for all modifications to existing major sources of VOC or NOX , unless at least one of the following conditions are met:

  (1) the proposed emissions increases associated with a project, without regard to decreases, is less than five tons per year (tpy) of the individual nonattainment pollutant in areas classified under Federal Clean Air Act (FCAA), Title I, Part D, Subpart 2 (42 USC, §7511) classified as Serious or Severe;

  (2) the proposed emissions increases associated with a project, without regard to decreases, is less than 40 tpy of the individual nonattainment pollutant in areas classified under FCAA, Title I, Part D, Subpart 1 (42 USC, §7502) and for those under FCAA, Title I, Part D, Subpart 2 (42 USC, §7511) classified as Marginal or Moderate; or

  (3) the project emissions increases are less than the significant level stated in Table I located in the definition of major modification in §116.12 of this title and when coupled with project actual emissions decreases for the same pollutant, summed as the project net, are less than or equal to zero tpy.

(d) In applying the de minimis threshold test, if the net emissions increases are greater than the significant levels stated in Table I located in the definition of major modification in §116.12 of this title, the following requirements apply.

  (1) The proposed facility or emissions unit shall comply with the lowest achievable emission rate (LAER) as defined in §116.12 of this title for the nonattainment pollutants for which the facility or emissions unit is a new major source or major modification except as provided in paragraph (3)(B) of this subsection and except for existing major stationary sources that have a potential to emit (PTE) of less than 100 tpy of the applicable nonattainment pollutant. For these sources, best available control technology (BACT) can be substituted for LAER. LAER shall otherwise be applied to each new facility or emissions unit and to each existing facility or emissions unit at which the net emissions increase will occur as a result of a physical change or change in method of operation of the unit.

  (2) All major stationary sources owned or operated by the applicant (or by any person controlling, controlled by, or under common control with the applicant) in the state must be in compliance or on a schedule for compliance with all applicable state and federal emission limitations and standards.

  (3) At the time the new or modified facility or emissions unit or facilities or emissions units commence operation, the emissions increases from the new or modified facility or emissions unit or facilities or emissions units must be offset. The proposed facility or emissions unit shall use the offset ratio for the appropriate nonattainment classification as defined in §116.12 of this title and shown in Table I located in the definition of major modification in §116.12 of this title. Internal offsets that are generated at the source and that otherwise meet all creditability criteria can be applied as follows.

    (A) Major stationary sources located in a serious or severe ozone nonattainment area with a PTE of less than 100 tpy of an applicable nonattainment pollutant are not required to undergo nonattainment new source review under this section, if the project increases are offset with internal offsets at a ratio of at least 1.3 to 1.

    (B) Major stationary sources located in a serious or severe ozone nonattainment area with a PTE of greater than or equal to 100 tpy of an applicable nonattainment pollutant can substitute federal BACT (as identified in §116.160(c)(1)(A) of this title (relating to Prevention of Significant Deterioration Requirements) for LAER, if the project increases are offset with internal offsets at a ratio of at least 1.3 to 1. Internal offsets used in this manner can also be applied to satisfy the offset requirement.

  (4) In accordance with the FCAA, the permit application must contain an analysis of alternative sites, sizes, production processes, and control techniques for the proposed source. The analysis must demonstrate that the benefits of the proposed location and source configuration significantly outweigh the environmental and social costs of that location.

(e) For sources located in the El Paso ozone nonattainment area as defined in 40 Code of Federal Regulations, Part 81, the requirements of this section do not apply to NOX emissions.
